Currently, only one form of comma character is being used as the tag separator when adding tags in a thread. However, there are a few variations of the comma character that are being used by one language or the other. While entering tags, it is very inconvenient to switch keyboard to use the comma other than the current language. Wikipedia suggests three different commas (, ، 、). I would like to suggest inclusion of all of them as the tag separator. XenTag addon added support for the Arabic comma on request that is being used in many RTL languages. Recently, I have seen some long tags in our forum that have Arabic comma in it, but they were treated as a single tag.
